Entity relationships can be implemented by creating a new entity in 1:m relationships with the original entities.
Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion.
A relationship is a connection between two tables that contain data: one column in each table is the basis for the relationship.
To see why relationships are useful, imagine that you track data for customer orders in your business.
